Selective laser melting (SLM) is widely used in making three-dimensional functional parts
layer by layer. Temperature magnitude and history during SLM directly determine the molten …

This paper presents a new numerical technique for simulating two-dimensional wind turbine
flow. The method, denoted as the 2D actuator surface technique, consists of a two …

The aerodynamics of a high-speed low-pressure turbine (LPT) cascade were investigated
under steady and unsteady inlet flows. The tests were performed at outlet Mach (M) and …

Prior to the detailed design of components, turbomachinery engineers must guide a mean-
line or throughflow design toward an optimum configuration. This process requires a …

In this two-part paper, a novel test-case for transonic low-pressure turbines (LPT) is
presented. The current study is a comprehensive report on the design, commissioning and …

In low-pressure turbines (LPT) at design point, around 60–70% of losses are generated in
the blade boundary layers far from end walls, while the remaining 30–40% is controlled by …

A study of the three-dimensional stator-rotor interaction in a turbine stage is presented.
Experimental data reveal vortices downstream of the rotor which are stationary in the …

Experimental data and numerical simulations are presented from a research turbine with low
aspect ratio nozzle guide vanes (NGVs). The combined effects of mechanical and …

In this paper, the effect of seal clearance on the efficiency of a turbine with a shrouded rotor
is compared with the effect of the tip clearance when the same turbine has an unshrouded …

The demand of further increased bypass ratio of aero engines will lead to low pressure
turbines with larger diameters rotating at lower speed. Therefore it is necessary to guide the …
